Seven months after the Battle of Yavin, the Imperial Star Destroyer Devastator undertook an evacuation of the Imperial garrisons on Ivarujar, a planet that had undergone a massive volcanic eruption. Lieutenant Commander Ciena Ree was charged with evacuating a local stormtrooper garrison in the capital city. After rescuing the stormtroopers, she managed to evacuate forty civilians before the city was completely overrun by lava. Ciena's troop transport barely managed to escape the firestorm and reached the Devastator. While Ciena's humanitarian gesture won her the respect of the Ivarujarians, she was reprimanded and disciplined by the Imperial Security Bureau Captain Ronnadam for not consulting her superiors about the civilian rescue.
